Patented June 17, 1952 CARDING ENGINE WITH SECONDARY TAKER-IN GeorgeClapperton, Bolton, England, ass'ignor to Nuclotex Limited, Bolton,England Application September 30, 1948,-Serial No. 52,009 In GreatBritain July 31, 1948 Claims.

This invention relates to improvements in carding engines for cotton orother fibres.

According to the invention a secondary takerin roller is arranged belowthe primary taker-in roller, the secondary taker-in roller being smallerin diameter and having a greater peripheral speed than the primaryroller and being so disposed in relation thereto and to the cardcylinder that it removes all or the greater part of the fibres from theprimary roller and delivers them to the card cylinder.

The secondary taker-in roller is covered with metal wire clothingsimilar to but preferably 'finer than that of the primary roller.

The invention is illustrated in and will be described with reference tothe accompanying drawing which shows a longitudinal section ofsufficient of a carding engine for the invention to be understood. V

In the drawing A is the usual card cylinder, a. the card cylinder shaft,B the travelling flats, C the primary taker-in roller, D the feed plateand d the feed roller all of which are of usual known construction andarrangement.

A secondary taker-in roller E is mounted below the primary taker-inroller C in bearings carried in the side frames of the machine.

These bearings are preferably adjustable to allow of adjustment of theroller in relation to the primary roller C and the cylinder A.

The secondary taker-in roller E is covered with metal wire clothing esimilar to but preferably finer than the clothing c of the primaryroller C.

The roller E is smaller in diameter than the roller C and is rotated ata greater surface speed than the latter roller. The two rollers C and Erotate in the same direction as each other but in the opposite directionto the rotation of the card cylinder A. Thus, the wires e of the rollerE are travelling in the opposite direction to the wires 0 of the rollerC at the point Where they interact.

Suitable diameters and speeds of rotation of primary taker-in roller Cand secondary taker-in roller E co-operating with a carding cylinder of50%" diameter rotating at 160 revs. per minute are: roller C 9%"diameter 400 revs. per minute, roller E 4%" 1260 revs. per minute. It isto be understood that these diameters and speeds are only given by wayof example and the invention is not limited thereto.

Mote knives c are arranged in the usual position below the primarytaker-in roller C and a casting C carrying the grid bars 0 extends fromthe front mote knive c to a position near the periphery of the secondarytaker-in roller E.

Mote knives e are arranged below the secondary taker-in roller E insubstantially the same relative position thereto as are the mote knife 6to the roller C and the space between the front mote knife e and thecard cylinder is covered by a curved metal casing E carrying transversegrid bars 6 A curved casing G, bolted or otherwise aflixed to the framesides, extends from the rear mote knife e to the casing C below theprimary takerin roller C and a making-up piece G of approximatelytriangular shape is arranged in the space formed between the twotaker-in rollers C and E and card cylinder A.

The fibres are fed to the primary taker-in roller C in the usual way bythe feed roller (1 and are carried round by the roller C to the pointwhere the latter meets the secondary taker-in roller E. The wires 6 ofthe roller E, which at this point are moving in the opposite directionto the wires 0 of the roller C, then remove most of the fibres from thewires 0 and carry them round passedthe casing G andmote knives e to thecard cylinder A the wire clothing of which removes them therefrom in theusual way. Any fibres not removed from the wires 0 of the primarytaker-in roller C by the wires e of the secondary taker-in roller E arecarried forward by the roller C to the card cylinder A.

A carding engine provided with a secondary taker-in roller C arrangedand operating as hereinbef'ore described has an additional cleaningeffect on the fibres and also produces a combing or paralleling actionthereon between the two taker-in rollers.

I claim:
